MNP issue

I have applied for Mobile Number Portability from AIRCEL network to AIRTEL Network. They accepted my request. And local reference verification started. In third attempt, my friend(Local reference) has given a positive response like he knows me for the past 3 years and we were working in same company and we were neighbours too. But even after that positive reply, the tele verifier from AIRTEL has registered the response as NEGATIVE. Now, i am not able to apply for New MNP request for the same number for another one month of time. If i ask AIRTEL, they are telling to get the refund of Rs. 50 and join in some other network. But i want to join in their network. Please help me to resolve the issue.
